Product Variations heading not correct on product page back-end Bug

Hi,

Having difficulty when doing product variations. First, the permalink when I change it refuses to change, perhaps this is the problem with the categories and tags?

But also, the old variations used "variations" in the header where you create them. See Screenshot. The new variations puts the name of the first variation as the name. This causes a problem on the front-end where it then shows that. Instead of asking the customer for a variation it titles it the first variation created. See Screenshots. I can only add one screenshot here see below this once it's posted. Thanks.
